A calculation I saw a couple of decades ago showed that the entire energy being used by the world then could be powered by a solar array 200 miles on a side. I think that figure is on the right order, then break that 40,000 sq. mi. into 100 pieces ... and each is 20 miles on a side. Compare that to the amount of sunlit desert in the world. Simple, obvious, self-explanatory. Of course, the fuel cost of solar is zero. The energy can be created anywhere there's sunlight. Consumed locally. And there's no waste. A threatening vision for the power brokers. They may say anything to have their way.
